  1. 1. Camera Modelling and Calibration with Machine Vision Applications

    Författare :Anders Ryberg; Bengt Lennartson; Anna-Karin Christiansson; Anders Heyden; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Camera model; Camera calibration; Fisheye camera; Catadioptric camera; Stereo vision; Other technology; Övriga teknikvetenskaper; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. LÄS MER

  3. 2. Multi-Camera Light Field Capture : Synchronization, Calibration, Depth Uncertainty, and System Design

    Författare :Elijs Dima; Mårten Sjöström; Roger Olsson; Ulf Assarsson; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Light field; Camera systems; Multiview; Synchronization; Camera calibration;

    Sammanfattning : The digital camera is the technological counterpart to the human eye, enabling the observation and recording of events in the natural world. Since modern life increasingly depends on digital systems, cameras and especially multiple-camera systems are being widely used in applications that affect our society, ranging from multimedia production and surveillance to self-driving robot localization.

  4. 3. Camera Modelling and Calibration for Machine Vision Applications

    Författare :Anders Ryberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Camera Calibration; Camera Modelling; Stereo Vision; Machine Vision; Pose Measurement; Computer Vision;

    Sammanfattning : This thesis describes camera based methods for determining positions and orientations of objects in 3D-space. These methods are useful in several applications where camera images are used for acquiring information about the surroundings, and the targeted application here is guiding robots using a camera mounted on the robot hand.

  5. 4. Beta Camera: Development and applications

    Författare :Kaj Ljunggren; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; medical instrumentation; tomography; radiology; Clinical physics; microchannel plate; radionuclides; scintillator; autoradiography; Beta Camera;

    Sammanfattning : A new detector for on-line digital detection of charged particles (beta-particles, conversion electrons and alpha-particles) from thin samples for rapid autoradiography has been developed; the Beta Camera. The device consists of a photon-sensitive detector (image photon detector, IPD); the main component of which is a microchannel plate. LÄS MER

  7. 5. Learning and Optimizing Camera Pose

    Författare :Lucas Brynte; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimization; structure-from-motion; camera pose estimation; machine learning;

    Sammanfattning : Plenty of computer vision applications involve assessing the position and orientation, i.e. the pose , of one or several cameras, including object pose estimation, visual  localization, and structure-from-motion. LÄS MER
